If two distinct chords, drawn from the point (α, β) on the circle x^2+y^2=α x+β y (where α β ≠ 0 ) are bisected by the y -axis, then
If two distinct chords, drawn from the point $\displaystyle (\alpha, \beta)$ on the circle $\displaystyle x^2+y^2=\alpha x+\beta y$ (where $\displaystyle \alpha \beta \neq 0$ ) are bisected by the $\displaystyle y$-axis, then
